Unfortunately Elliott, your 1007's symptoms sound (sorry!) all too familiar. You may find that eventually a factory reset may suddenly work after several tries, but this appears the start of the well trodden path to HDMI board failure. Switching the unit off and pulling the plug may also work for a while too.
Other symptoms include: no little speaker icons on the front display; non responsive when switched to a different input signal type or decoder and inability to generate any speaker test noise. When I was able to bring my unit "back from the dead" with a factory reset, I didn't switch it off for weeks for fear it wouldn't come back. Despite this, total failure still occurred after about a month. You can read my little saga starting at this post
, and see if your experience is similar.
I suggest that you keep trying to bring it back to life for us long as possible to satisfy yourself that it is (as Keith says) completely FUBAR. This will ensure that the repair centre can "replicate the fault" straight away. As I understand it, the HDMI board failure is a recognised manufacturing defect and Onkyo has in the past been authorising repairs under a one-off extension to the warranty. Others who have relied on this may be able to confirm this. (Mine was repaired under 3 year warranty, so I'm not 100% sure.)
I think I did notice the greyed out remote controller setup, but didn't take much notice. I suspect this is because the factory reset will have wiped your input/output assignments and they're needed to set up the modes and activities under that menu item.
Good luck with it all Elliott.
